Specification of Letters Patent.

Patented Aug. 17, 1915.

Application filed November 18, 1914. Serial No. 872,848.

To all 107mm it may concern Be it known that I, Snnarnvo GALLI, a-

subjeet of the Kingdom of Italy, but have within two years last past declared my intention to become a citizen of the United States, residing at Mulberry, in the county of Crawford and State of Kansas, have invented certain new and useful Improvements in Safety Dogs or Catches for Dumping-Cages; and I do hereby declare the following to be a full, clear, and exact deseription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, refer ence being had to the accompanying draw ings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in attachments to pit cars and the object in view is to produce a simple and" efficient device for securely holding loaded and unloaded pit cars upon dump .eages, means being provided for releasing the car when it is desired to have the same leave the cage.

My invention comprises various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which:

Figure '1 is a side elevation of my improved apparatus. Fig. 2 is a top plan view. Fig. 3 is a view in elevation of one of the plates removed. Fig. 4 is a cross sectional view in line 41 of Fig. 1. Fig. 5 is a view in elevation showing the ratchet operated means for releasing the springpressed locking bolt, and Fig. 6 is a view in elevation of a spring-pressed depressible ratchet actuating member.

Reference now being had to the details of the drawings by numeral, 1, 1 designate two metallic plates having flanges 2 through apertures in which the plates may be fastened to the floor of a cage. Said plates have oppositely disposed recesses 8 formed therein in which a spring-pressed depressible block 1 is mounted, said block being provided with an aperture 5 and the under surface of said block is recessed for the reception of the inner ends of the two levers 6 and 7 respectively, which are mounted at their outer ends upon the pivotal pins 8 passing through the registering apertures in the two plates when the latter are fastened together. A spring 9 is adapted to be fastened to the floor of the cage underneath said block and its ends bear against the under edge of each of said levers 6 and 7, serving to normally hold their inner ends yieldingly against the top wall of the recess in said block 4:, the oilice of said spring be ing to normally hold the block at its farthest upper throw to engage between the axles of the pit car to hold the same upon the cage. Levers 10 and 11 are pivotally mount-v ed at their inner ends upon the pivotal pins 12 which pass through registering apertures of the two plates and the upper edge of each of said levers 10 and 11 is provided with a notch 14: adapted to contact with the inwardly projecting lugs 15 upon the inner faces of the two plates and which lugs serve to limit the upper throw of each of said levers 10 and 11. The under edge of the levers 10 and 11 bear against respectively the upper edges of the levers 6 and 7 and are provided for the purpose of causing said levers G and 7 to tilt downward when it is desired to draw down the block 41 out of its engaging relation between the axles of the car. The ends of the lovers l0 and 11 project beyond the ends of the plates and form means whereby one or the other may be depressed to cause the block to be drawn down in the recesses between the plates.

A boxing, designated by numeral 1 1* and preferably of metalis fastened to one of said plates and has fastened thereto a spring 16, the forward free end of which at 17 is curved slightly. and pin 1.8 projects from the spring 16 and is normally held by the spring carrying the same in the aperture 19 formed in one of said plates and also to engage the aperture 5 in the block- 1 when the block a is depressed so that said aperture 5 will be in registration with the aper ture 19 to hold the block down so that it will be flush with or below the upper edges of the plates or out of the path of the axles of the car.

Journaled upon a pin 20 carried by one of the plates is a ratchet wheel 21 having integral cam-shaped fingers 22, each beveled and adapted, as a partial rotary movement is imparted to the ratchet wheel, to engage the outwardly curved end 17 of said spring again depresses the lever 29.

for the purpose of throwing the pin carried by the spring out of engagement with the aperture 5 formed in the block 4 and which will allow the block a to be thrown up by the spring underneath the same to a locking position.

A depressible meral 29, is pivotally mounted upon a'pin 25 and the upper edge of the lever 29 is inclined from its central portion toward its end and is held at its farthest upper limit by means of a spring 30 fastened to, the boxing and positioned within the same. The

free end of the lever 29 is shouldered as at 31 and is adapted to bear against a projecting portion of the boxing 32 to hold the same within the boxing, and a finger 33 projects from the under edge of the lever 29 and is designed, when the lever 29 is depressed, to engage the ratchet wheel and impart a partial revolution thereto, so that one of said cam fingers will engage the spring carrying pin and throw the same out of engagement with the block 4:. A resilient pawl 3a is fastened to the inside of the boxing and engages the ratchet wheel and serves to hold the same from rotating in one direction. 7

In operation, the car retaining block being normally held down out of a locked relation by the spring-pressed pin engaging the registering apertures inthe plate and block, the car may be passed over the plates and, when the forward axle of the car comes in contact with the lever 29, the same will be depressed and a finger upon. the latter will cause the ratchet wheel to make a partial rotation and a cam finger engaging the outwardly curved part 17 of the spring will cause the pin 18 to be thrown out of the aperture in the block t andthe spring underneath the block will throw the latter up between the axles, thus locking the car upon the cage. When it is desired to release the block, the operator by pushing down upon the projecting end of either of the levers 10 and 11, may cause the block 4t to be drawn down between the-plates and the pin carried by said spring will be thrown into the aperture in the block 4: and hold the block depressed, thus allowing the car to pass oh the cage without interference with the block or other parts of the mechanism until the rear axle of the car comes in contact with and As another car comes upon the cage and when the for ward axle of the car comes in contact with V the lever 29, the finger upon the latter will cause the block to be released and which will be thrown by the spring bearing against the same between the axles, thus locking the car in position upon the cage.

By the provisionof a device embodying the features of my invention a simple and lever, designated by nuspring-pressed lever.

What I claim to be new is: 7 V 1. An apparatus for locking pit cars upon self-dumping cages "comprising plates secured to the floor of the cage, a spring-V pressed locking-block mounted between said plates, levers adapted, as pressure is applied to the free end thereof, to cause the block to:

be drawn downbetween'the plates, a springpressed pin adapted to engage and hold. the block down, a ratchet wheeland means connected thereto forv releasing said spring Sressed )in and a de ressibles 'rin ressed lever adapted to impart a partial rotary movement to the ratchet wheel.

2. An apparatus for locking pit cars upon self-dumping cages comprising plates secured to the floor of the cage, a springpressed locking block mounted between said cages, levers adapted, as pressure is applied to the free ends thereof,'to cause the block to be drawn down between the plates, a pin adapted to engage and hold the block down, a spring carrying said pin, a ratchet wheel, cam fingers projecting therefrom and adapted to throw the pin carried by said spring out of engagement with said block as the ratchet wheel is rotated, and a depressible spring-pressed lever for rotating the ratchet wheel.

An apparatus for locking pit cars upon self-clumping cages comprising two plates vadapted to be fastened to the floor of the cage and having recesses upon their adjacent faces, a spring-pressedlocking hlock movable within said recesses, spring-pressed levers, the free ends of which are adapted to be depressed to cause the block to be drawn down into said recesses, one of said plates 7 and block being provided with registering apertures, a spring with a pin projecting In testimony whereof I hereunto afi'ix my signaturein presence of two witnesses.
